Firstly, CuO nanoparticles, cubic and petal-shaped CuO nanostructures were prepared by chemical synthesis, pyrolysis and hydrothermal methods under different conditions. Then, the morphology and size of the prepared CuO nano-materials with different morphologies were characterized by scanning electron microscopy (SEM) and transmission electron microscopy (TEM). Finally, these CuO nano-materials were prepared into gas sensing sensors and their gas sensing properties were tested by gas detector.It is found that the cubic and petal-shaped CuO nanostructures have higher oxidizing affinity and higher gas sensing sensitivity. Among them, the petal-shaped CuO nanostructure exhibits the highest gas sensing sensitivity. This research plan of preparing CuO nano-materials with different morphologies and studying their gas sensitivity can provide new ideas and methods for preparing high-performance gas sensing sensors.精品文档---下载后可任意编辑Keywords: CuO nano-materials; morphology control; gas sensitivity; gas sensing sensor
